this is coming from cbs news. more americans, as you can see there, 57% are in favor of more strict gun control laws versus 39% in april. that is an incredible jump. and you look at even members of the nra, and they say that 74% say there should be background checks on all purchasers. 74% only after gun safety training, and you see the screen there. you know, you talk about arming, or the possibility of arming teachers and school officials is one thing, and maybe some of them want to do that. there's another big point about whether it works. there was an armed good in littleton, colorado, at columbine. that didn't stop those shooters from going on a rampage, 15 dead. there was a police station on the campus of virginia tech. that didn't stop that gunman. and a lot of people think these attacks happened so quickly, these gunman are so brazen, there's nothing anyone can do to stop that. what do you say to that? >> i introduced legislation to allow professionors wors who ha concealed carry permits to carry on campus
